Scientific goals and experimental approach
Primary scientific goal: - investigation of composition and structure of lunar regolith in the landing area Experimental method: - mass-spectrometry of secondary and reflected ions and neutral atoms Specifics of experiment: - using the solar wind as primary illuminating beam - mapping the landing area by imaging of secondary ions and neutral atoms

Investigation plan through mission lifetime
· Instrument operates in automatic mode · Instrument does not work during cruise to the moon · Special initialization procedure required after landing · Instrument operates during mission's lifetime · Instrument operates from dawn to 2 hours after sunset · Instrument is off during the drilling


Data output

Average data output

2 Kbits/sec

Total data output for lunation 2 Gbits


Other requirements to spacecraft systems (manipulator)

· Manipulator not required


Expected results of experiment

· Minimum scientific success
- average mass composition of regolith averaged over nearby landshaft

· Full success - regolith composition variations over ~ 10 spots near landing site structural characteristics of regolith


Interaction with other instruments
· Simultaneous magnetic field measurements are very
important
